3 Earnings Before Interest, Taxes, Depreciation, Depletion and Amortization and the Noncash Earnings/Loss from Nonconsolidated Equity Affiliates, or Adjusted EBITDA, is a non-GAAP financial measure. See Appendix to this earnings release for a reconciliation to net earnings attributable to Martin Marietta.

Ward Nye, Chairman and CEO of Martin Marietta, stated, “For the first three months of the year, Martin Marietta delivered strong financial and operational performance, generating Adjusted EBITDA of $149 million. We established a new first-quarter record for consolidated revenues, as product demand led to improved shipments and pricing across most of our Building Materials business. Notably, production efficiencies improved our year-over-year per unit aggregates cost. While this is what we aim for, as lower unit costs improve operating margins, in the current quarter, this lower unit cost served to reduce aggregates inventory valuation. This year-over-year impact alone lowered earnings per share by $0.18. Further, the prior-year’s first-quarter benefitted from a change in tax election for a subsidiary of $0.21 per share. Understanding those circumstances largely contextualizes our impressive first-quarter 2020 performance. Additionally, we strengthened the Company’s balance sheet and cash position through the early March issuance of $500 million of 2.5% senior notes due in 2030. While our solid first-quarter performance provided a promising start to 2020, we recognize this will now be a challenging year for our country, customers, communities and industry as a whole. Thus, given the unprecedented level of uncertainty surrounding the length, breadth and severity of the coronavirus (COVID-19) pandemic, we have withdrawn our previously-issued full-year 2020 guidance and will not update it at this time. With that said, we remain confident that the attractive underlying market fundamentals and long-term secular growth trends in our key geographies, both of which underpinned the Company’s record 2019 performance and strong first-quarter 2020 results, remain intact and will be evident once again as the U.S. economy stabilizes and recovers.

“Our Company’s commitment to operational excellence, disciplined approach to growth and tradition of preparedness have positioned us well to weather this period of uncertainty. We have thoughtfully developed and consistently executed on our strategic plans, positioning our business as an aggregates leader in attractive high-growth geographies, aligning our product offerings to leverage strategic cement and targeted downstream opportunities and prudently allocating capital while maintaining financial flexibility. In doing so, we have built a business that is durable and resilient. While Martin Marietta is not immune to the impact of COVID-19, we believe our Company is well prepared to meet the current and coming challenges.

“Importantly, the Company’s balance sheet remains healthy and we have ample liquidity for the foreseeable future. Martin Marietta, along with our customers, continues to operate as an “essential business” in most jurisdictions and, through the end of April, we have seen minimal disruption to our operations, workforce and supply chains from the effects of COVID-19 and related government agency responses. Nonetheless, we anticipate product demand will soften in the coming months, as businesses and governments prioritize actions in response to COVID-19. Our team has plans for a variety of scenarios and will react appropriately to changing conditions. We will continue to closely monitor the situation and focus on safeguarding our stakeholders’ health and well-being, operating safely and efficiently, preserving liquidity and aligning costs with customer demand.”

Mr. Nye concluded, “Consistent with our values of safety, integrity, excellence, community, and stewardship, Martin Marietta is committed to providing the products and services our communities need. I am enormously proud of the determination, professionalism and devotion of our Martin Marietta employees who are working each and every day. Their dedication supports our communities and business partners who are persevering through the impacts of the current crisis. We remain appropriately focused on our tactical day-to-day responsibilities and ever mindful of the values and strategies that have driven our long track-record of success. Guided by our shared commitment to the world-class attributes of our business, safety, operational excellence, cost management, and the disciplined execution of our proven strategic plan, Martin Marietta has the right strategies, priorities and team to responsibly navigate through these challenging times and drive sustainable long-term growth and shareholder value.”

The COVID-19 pandemic and related public policy responses largely began in mid-March in the United States. As such, first-quarter results and trends described in this earnings release may not be indicative of the Company’s future performance.

Building Materials Business

First-quarter operating results demonstrated the strength of overall demand, most notably in Colorado, Iowa, Indiana and Maryland, against a challenging prior-year comparison. The aggregates, cement and downstream operations in Texas, the Company’s largest state by revenue, experienced project delays as the Dallas/Fort Worth area experienced record first-quarter precipitation. Additionally, Georgia, the Company’s fourth-largest state by revenue, experienced its sixth wettest first quarter in 125 years.

Martin Marietta’s first-quarter aggregates shipments by end use are as follows (all comparisons are versus the prior-year quarter):

Aggregates shipments to the infrastructure market increased, driven by large projects in Texas, Colorado, Iowa and Indiana. The infrastructure market accounted for 32 percent of first-quarter aggregates shipments, which is below the Company’s most recent ten-year annual average of 45 percent but consistent with historical first-quarter trends.

Aggregates shipments to the nonresidential market increased modestly following double-digit growth in commercial and heavy industrial construction activity in the prior-year quarter. The Company continued to benefit from distribution center, warehouse and data center projects in key geographies, including Texas, Colorado, Georgia, Florida and Iowa, as well as the early phases of several large energy-sector projects along the Gulf Coast. The nonresidential market represented 36 percent of first-quarter aggregates shipments.

Aggregates shipments to the residential market declined slightly when compared with the robust growth in homebuilding activity in the prior-year quarter. Ongoing homebuilding activity in Texas and Georgia was hindered by significant rainfall during first-quarter 2020. The residential market accounted for 25 percent of first-quarter aggregates shipments.

The ChemRock/Rail market accounted for the remaining 7 percent of first-quarter aggregates shipments. Volumes to this end use increased, driven by improved ballast shipments to the Class I western railroads and higher agricultural lime shipments.

Magnesia Specialties product revenues decreased 13.4 percent to $59.9 million, consistent with expectations and driven by continued declines in chemicals products as international customers rationalize inventory levels. Lime shipments to the steel industry were flat. Effective cost containment measures, coupled with lower energy costs, led to a 500-basis-point expansion in product gross margin to 43.5 percent.

Consolidated

Total cost of revenues for first-quarter 2020 included $2.0 million of expense for the implementation of a new paid time off policy for employees.

Other operating income, net, for the prior-year quarter included the reversal of $4.2 million of accruals for unclaimed property contingencies.

Other nonoperating expense, net, for first-quarter 2020 included $5.6 million to finance third-party railroad maintenance in exchange for a federal income tax benefit of $6.9 million.

The Company recorded a discrete income tax benefit of $13.2 million in the prior-year quarter related to a change in tax election for a subsidiary.

Earnings per diluted share declined $0.27, primarily driven by the year-over-year impact of lower unit production costs on aggregates inventory standards of $0.18 per share and the prior-year benefit from a change in tax election for a subsidiary of $0.21 per share.

Liquidity and Capital Resources

Cash provided by operating activities was $106.7 million in first-quarter 2020 compared with $117.9 million for the same period in 2019.

Cash paid for property, plant and equipment additions was $104.1 million in 2020.

In March 2020, the Company issued $500 million of 2.5 percent senior notes due in 2030. The Company intends to use the net proceeds for the repayment of $300 million of floating rate notes maturing in May 2020 and general corporate purposes.

The Company had $424.0 million of cash on hand, along with $757.7 million of unused borrowing capacity on its existing credit facilities as of March 31, 2020. Excluding the $300 million earmarked for the May 2020 debt repayment, the Company had approximately $880 million of available liquidity at March 31, 2020.

Commitment to Enhance Long-Term Shareholder Value

Martin Marietta is dedicated to disciplined capital allocation that preserves the Company’s financial flexibility and further enhances shareholder value. The Company’s capital allocation priorities currently remain unchanged and include value-enhancing acquisitions that promote the successful execution of the Company’s strategic growth plan, organic capital investment and the return of cash to shareholders through meaningful and sustainable dividends and share repurchases.

The Company has returned $1.7 billion to shareholders in the form of dividend payments and share repurchases since announcing a 20 million share repurchase authorization in February 2015. During first-quarter 2020, the Company repurchased 210,600 shares of common stock pursuant to its share repurchase authorization. As of March 31, 2020, 13.5 million shares remained under the current repurchase authorization and 62.2 million shares of Martin Marietta common stock were outstanding.

Full-Year Outlook

The Company has withdrawn its 2020 full-year guidance issued on February 11, 2020, given the economic disruptions driven by the COVID-19 pandemic and the multiple measures put in place to treat and minimize the spread of the virus. We cannot reliably forecast the impact these disruptions will have on the U.S. economy, the timing and benefits of related governmental actions and, more specifically, demand for the Company’s products and services. While most jurisdictions have deemed the supply of construction materials as an essential business, Martin Marietta believes its industry will likely experience lower overall demand during the COVID-19 crisis. However, the magnitude of decline and speed and rate of recovery are likely to vary by construction end-use market and geography.

Of the Company’s three primary end uses, the outlook for infrastructure construction, particularly for aggregates-intensive highways and streets, is expected to be the most near-term resilient. While the majority of the United States has currently been ordered to shelter in place, most state Departments of Transportation (DOTs) are currently operational and continue to advance transportation projects, capitalizing on the reduction of vehicles on the road and related traffic congestion. Florida, for example, recently announced plans to accelerate $2.1 billion of critical transportation projects. That said, state DOTs are experiencing lower revenue collections and states may have other short-term funding needs relating to the COVID-19 impact that may decrease the scale and/or postpone the timing of future construction. Industry representatives are actively engaging with Congress to address surface transportation infrastructure in the “Phase 4” emergency relief and economic recovery COVID-19 legislation, including an immediate $49.95 billion in flexible federal funding to offset an estimated 30 percent loss in state transportation revenues in the next 18 months and the passage of a comprehensive major surface transportation reauthorization package.

Nonresidential construction activity on existing projects has continued in most regions. However, according to an April 2020 survey published by the Associated General Contractors of America, an overwhelming number of respondents indicated that commercial projects in the design or planning stages are being delayed or canceled. Unlike commercial activity, industrial construction is not expected to experience significant near-term disruption from COVID-19. Warehouses, distribution centers and data centers are expected to perform relatively well in the current environment as businesses increase e-commerce activity, secure regional supply chains and become more reliant on cloud and network services. Similarly, large energy-sector projects along the Gulf Coast of Texas that are actively underway are expected to continue.

Residential construction activity is expected to decline in 2020, as homebuilders and homebuyers delay plans in the wake of unprecedented economic uncertainty. Supported by third-party forecasts, management believes the residential decline will be widespread but not as persistent as the period of low activity seen during the Great Recession as Freddie Mac estimates that 2.5 million housing units are needed to address the current nationwide housing shortage. This situation is particularly evident in states with significant undersupply, including Texas, Colorado, North Carolina and Florida. On a national level, housing starts remain below the 50-year annual average of 1.5 million despite notable population gains.

Investors are cautioned that all statements in this release that relate to the future involve risks and uncertainties, and are based on assumptions that the Company believes in good faith are reasonable but which may be materially different from actual results. These statements, which are forward-looking statements under the Private Securities Litigation Reform Act of 1995, give the investor the Company’s expectations or forecasts of future events. You can identify these statements by the fact that they do not relate only to historical or current facts. They may use words such as “guidance”, “anticipate”, “expect”, “should”, “believe”, “will”, and other words of similar meaning in connection with future events or future operating or financial performance. Any or all of our forward-looking statements here and in other publications may turn out to be wrong.

The Company’s outlook is subject to various risks and uncertainties, and is based on assumptions that the Company believes in good faith are reasonable but which may be materially different from actual results. Factors that the Company currently believes could cause actual results to differ materially from the forward-looking statements in this release (including the outlook) include, but are not limited to: the ability of the Company to face challenges, including those posed by the COVID-19 pandemic and implementation of any such related response plans; the resiliency and potential declines of the Company’s various construction end-use markets; the potential negative impact of the COVID-19 pandemic on the Company’s ability to continue supplying heavy-side building materials and related services at normal levels or at all in the Company’s key regions; the duration, impact and severity of the impacts of the COVID-19 pandemic on the Company, including the markets in which we do business, our suppliers, customers or other business partners as well as on our employees; the economic impact of government responses to the pandemic; the performance of the United States economy, including the impact on the economy of the COVID-19 pandemic and governmental orders restricting activities imposed to prevent further outbreak of COVID-19; shipment declines resulting from economic events beyond the Company’s control; a widespread decline in aggregates pricing, including a decline in aggregates shipment volume negatively affecting aggregates price; the history of both cement and ready mixed concrete being subject to significant changes in supply, demand and price fluctuations; the termination, capping and/or reduction or suspension of the federal and/or state gasoline tax(es) or other revenue related to public construction; the level and timing of federal, state or local transportation or infrastructure or public projects funding, most particularly in Texas, Colorado, North Carolina, Georgia, Iowa and Maryland; the impact of governmental orders restricting activities imposed to prevent further outbreak of COVID-19 on travel, potentially reducing state fuel tax revenues used to fund highway projects; the United States Congress’ inability to reach agreement among themselves or with the Administration on policy issues that impact the federal budget; the ability of states and/or other entities to finance approved projects either with tax revenues or alternative financing structures; levels of construction spending in the markets the Company serves; a reduction in defense spending and the subsequent impact on construction activity on or near military bases; a decline in the commercial component of the nonresidential construction market, notably office and retail space, including a decline resulting from economic distress related to the COVID-19 pandemic; a decline in energy-related construction activity resulting from a sustained period of low global oil prices or changes in oil production patterns or capital spending in response to this decline, particularly in Texas; increasing residential mortgage rates and other factors that could result in a slowdown in residential construction; unfavorable weather conditions, particularly Atlantic Ocean and Gulf of Mexico hurricane activity, the late start to spring or the early onset of winter and the impact of a drought or excessive rainfall in the markets served by the Company, any of which can significantly affect production schedules, volumes, product and/or geographic mix and profitability; whether the Company’s operations will continue to be treated as “essential” operations under applicable government orders restricting business activities imposed to prevent further outbreak of COVID-19 or, even if so treated, whether site-specific health and safety concerns might otherwise require certain of the Company’s operations to be halted for some period of time; the volatility of fuel costs, particularly diesel fuel, and the impact on the cost, or the availability generally, of other consumables, namely steel, explosives, tires and conveyor belts, and with respect to the Company’s Magnesia Specialties business, natural gas; continued increases in the cost of other repair and supply parts; construction labor shortages and/or supply‐chain challenges; unexpected equipment failures, unscheduled maintenance, industrial accident or other prolonged and/or significant disruption to production facilities; increasing governmental regulation, including environmental laws; the failure of relevant government agencies to implement expected regulatory reductions; transportation availability or a sustained reduction in capital investment by the railroads, notably the availability of railcars, locomotive power and the condition of rail infrastructure to move trains to supply the Company’s Texas, Colorado, Florida, Carolinas and the Gulf Coast markets, including the movement of essential dolomitic lime for magnesia chemicals to the Company’s plant in Manistee, Michigan and its customers; increased transportation costs, including increases from higher or fluctuating passed-through energy costs or fuel surcharges, and other costs to comply with tightening regulations, as well as higher volumes of rail and water shipments; availability of trucks and licensed drivers for transport of the Company’s materials; availability and cost of construction equipment in the United States; weakening in the steel industry markets served by the Company’s dolomitic lime products; trade disputes with one or more nations impacting the U.S. economy, including the impact of tariffs on the steel industry; unplanned changes in costs or realignment of customers that introduce volatility to earnings, including that of the Magnesia Specialties business that is running at capacity; proper functioning of information technology and automated operating systems to manage or support operations; inflation and its effect on both production and interest costs; the concentration of customers in construction markets and the increased risk of potential losses on customer receivables; the impact of the level of demand in the Company’s end-use markets, production levels and management of production costs on the operating leverage and therefore profitability of the Company; the possibility that the expected synergies from acquisitions will not be realized or will not be realized within the expected time period, including achieving anticipated profitability to maintain compliance with the Company’s leverage ratio debt covenant; changes in tax laws, the interpretation of such laws and/or administrative practices that would increase the Company’s tax rate; violation of the Company’s debt covenant if price and/or volumes return to previous levels of instability; downward pressure on the Company’s common stock price and its impact on goodwill impairment evaluations; the possibility of a reduction of the Company’s credit rating to non-investment grade; and other risk factors listed from time to time found in the Company’s filings with the SEC.

You should consider these forward-looking statements in light of risk factors discussed in our Annual Report on Form 10-K for the year ended December 31, 2019 and other periodic filings made with the SEC. All of our forward-looking statements should be considered in light of these factors. In addition, other risks and uncertainties not presently known to us or that we consider immaterial could affect the accuracy of our forward-looking statements, or adversely affect or be material to the Company.
